It is important to understand that
as the laws vary from State to State, some are actually unconstitutional as
written. In most cases, State officials realize this and do not question a
parent filing an exemption since they do not want litigation. However, other officials, such as NY State are notorious for
grilling parents in an attempt to determine sincerity and whether or not the
belief is actually religious in nature. Still others have attempted to redefine what a particular religion does or does not
teach.
